Less than two weeks I started coming down with cold symptoms. Prior to this my son and my wife were going through sore throats, coughing, etc. Some viral epidemic. One morning I woke up with sore nasopharynx and thick yellow mucus. General ill feeling, malaise, mild non-productive cough. Next day or some I accidentally noticed some tenderness on the lower part of my neck and what felt like an inflamed node. Tenderness lasted for couple of days and of course I was viciously palpating the area, and still do up until now, about 20 times/day. I cannot say for sure whether it is a lymph node/muscle ridge, etc. Tiny, thin, movable along with a ligament, easily movable, protuberance. Went to GP, she could not feel anything, when I pointed it out she was still not sure, and brushed it off as possibly reactive node. Ordered full blood work and I insisted on chest x-ray. Everything came back clear. I demanded ENT referral and neck ultrasound. Last neck ultrasound was done February of this year and was negative. ENT felt the neck, checked everything out and claimed what I felt was some muscle irregularity as it was too thin and elusive to touch. I felt great for about 2 hours, now I'm in full panic mode again about it being something bad. Now I will be getting ultrasound done and see assistant professor of head/neck surgery at University Hospital. When in panic, it feels enlarged and increasing in size to me. When I take xanax to calm myself down, it feels normal, and not lymph node looking. I lost a lot of weight since April, over 40 lbs as I was dieting/exercising regularly. My neck feels much thinner and everything is easily palpable. Please tell me how to stop this insane behavior? My parents told me it feels like muscle/ligament as well. I'm going through hell mentally picturing worst case scenarios. Please give some some rational advise.
